Add relational-jdbc to helm (#1937)
Motivation for the Change
Polaris needs to support relational-jdbc as the default persistence type
for simpler database configuration and better cloud-native deployment
experience.
Description of the Status Quo (Current Behavior)
Currently, the Helm chart only supports eclipse-link persistence type as
the default, which requires complex JPA configuration with persistence.xml
files.
Desired Behavior
Add relational-jdbc persistence type support to Helm chart
Use relational-jdbc as the default persistence type
Inject JDBC configuration (username, password, jdbc_url) through
Kubernetes Secrets as environment variables
Maintain backward compatibility with eclipse-link
Additional Details
Updated persistence-values.yaml for CI testing
Updated test coverage for relational-jdbc configuration
JDBC credentials are injected via QUARKUS_DATASOURCE_* environment
variables from Secret
Secret keys: username, password, jdbc_url
